This is a complete reference for integrating Apollo iOS into Swift projects. It walks you through the full lifecycle: adding the SDK via SPM, configuring codegen with the canonical swiftPackage + relative setup, wiring up ApolloClient with auth interceptors, writing queries and mutations from SwiftUI views, and generating test mocks only when you need them. The skill is opinionated in the right ways: it defaults you to modern patterns (v2+, Swift concurrency, single shared client), warns against auto-running codegen in Xcode build phases because it tanks compile times, and puts auth logic in interceptors instead of scattered across view code. If you're building a GraphQL app on Apple platforms, this gives you the architecture decisions and the step-by-step wiring in one place.
